The histograms below show the heights (in meters) of the tallest buildings in China and the United States.
Which pieces of information can be gathered from these histograms?
Choose all answers that apply:
Choose all answers that apply:
(Choice A)
A
The United States has the tallest building of these two countries.
(Choice B)
B
China has more buildings over 390390390 meters tall.
(Choice C)
C
None of the above
Information on the number of tall buildings and their heights in China and the United States can be interpreted from the histograms, with specific focus on the tallest buildings and the number surpassing the 390-meter mark.
Explanation:From the provided histograms comparing the heights of the tallest buildings in China and the United States, several pieces of information can be gathered. If the histograms indicate that the tallest bar on the chart for China is over the 390-meter mark and more numerous compared to the United States' histogram, then Choice B would be correct, indicating that China has more buildings over 390 meters tall. To verify Choice A, we would need to look at the highest point on both histograms; if the highest bar on the U.S. histogram extends further than the Chinese one, then it would mean the United States has the tallest building of the two. Without seeing the histograms, these judgments are based on typical interpretations of histogram data.
When considering data on tall buildings such as the number of stories and their height, constructing a histogram can help illustrate the frequency distribution of these heights. For example, using the rule of thumb that one story is approximately equal to the height of two adult humans, it is possible to establish some basic estimates for building heights. However, for detailed statistical analysis, including the identification of linear relationships or outliers, the data would need a closer examination, possibly using a least-squares or best-fit line.
Eve knits scarves for her online store. This week she has already knitted 9 scarves. There are 2 days left in the work week. She set
a goal for herself to knit at least 15 scarves and at the most 21 scarves this week Eve wants to know how many scarves she
should knit each day to meet her goal
Which inequality represents the given situation?
Final answer:
Eve should knit between 3 and 6 scarves each day for the remaining 2 days to meet her goal of knitting at least 15 and at most 21 scarves for the week. The inequality that represents this situation is 3 \<= x \<= 6.
Explanation:
Eve has knitted 9 scarves and wants to knit at least 15 and at most 21 scarves for the week. With 2 days of the workweek left, we need to find out how many scarves she should knit each day to meet her goal. Let's denote x as the number of scarves Eve knits each day for the next two days.
Since Eve has already knitted 9 scarves and wants to knit at least 15, the minimum number of additional scarves she needs to knit is 15 - 9 = 6. So, in 2 days, she must knit at least 6 scarves. This gives us the inequality 2x ≥ 6.
Similarly, the maximum number of scarves Eve aims to knit is 21. Therefore, the maximum number of additional scarves she can knit is 21 - 9 = 12. This leads us to the inequality 2x ≤ 12.
Combining both inequalities, we get 3 ≤ x ≤ 6, which tells us that Eve needs to knit between 3 and 6 scarves each day to meet her goal.

Answer:
1) 2/7; 43; 3/7
2) C
3) 30; 30; 10; is not; 10; is not
Step-by-step explanation:
1) y + 4/7 = 6/7
y = 6/7 - 4/7
y = 2/7
17 + b = 60
b = 60 - 17
b = 43
6/7 = m + 3/7
m = 6/7 - 3/7
m = 3/7

How many teenagers should be in the sample
Answer:
THEREFORE
Step-by-step explanation:
THERE SHOULD BE 7 TEENAGERS IN THE SAMPLE.
HOPE, THIS MAY HELP YOU BRO!!..
The sample should include 18 teenagers, as they constitute 60% of visitors aged 13-19 among the total sample of 30.
To determine the number of teenagers that should be in the sample, we first need to calculate the proportion of teenagers among the total visitors and then apply that proportion to the sample size.
From the cumulative frequency table, we can see that:
- The total number of visitors is 350.
- The number of teenagers (ages 13-19) is 210.
The proportion of teenagers among all visitors is:
[tex]\[\frac{\text{Number of teenagers}}{\text{Total number of visitors}} = \frac{210}{350}\][/tex]
Now, we need to apply this proportion to the sample size of 30 to find out how many teenagers should be in the sample:
[tex]\[\text{Number of teenagers in the sample} = \text{Proportion of teenagers} \times \text{Sample size}\][/tex]
[tex]\[\text{Number of teenagers in the sample} = \frac{210}{350} \times 30\][/tex]
[tex]\[\text{Number of teenagers in the sample} = \frac{3}{5} \times 30\][/tex]
[tex]\[\text{Number of teenagers in the sample} = 18\][/tex]
So, there should be 18 teenagers in the sample.

Find the value of X.
Answer:
x=37
Step-by-step explanation:
We know that the angles in a triangle must add to 180 degrees
So, the three angles: x, 3x-5 and x must be equal to 180
x+3x-5+x=180
Combine like terms
x+3x+x-5=180
5x-5=180
Add 5 to both sides
5x=185
Divide both sides by 5
x=37
Please answer~ 25 points :p
Answer:
y=15
Step-by-step explanation:
We know that the angles in a triangle add to 180 degrees
∠ABC+∠BAC+∠ACB=180
We don't know what ∠ACB is, but we know it is on a straight line with another angle (∠ACD). They are supplementary, and must add to 180
∠ACB+ ∠ACD=180
∠ACB+146=180
Subtract 146 from both sides
∠ACB=34
Now, we know ∠ABC is 4y+8, ∠BAC is 5y+3 and∠ACB is 34, so we can substitute them in
∠ABC+∠BAC+∠ACB=180
4y+8+5y+3+34=180
Combine like terms
4y+5y+8+3+34=180
9y+45=180
Subtract 45 from both sides
9y=135
Divide both sides by 9
y=15
The equation (x+h)(x+5)=0 has solutions of -5 and 6. What is the value of h.
Answer:
h = -6
Step-by-step explanation:
To solve this problem, plug in the values of either -5 or 6 into the equation for x. Then, simplify. Let's begin by plugging 6 in.
(6 + h)(6 + 5) = 0
I like to use the acronym FOIL for problems like these: first, outside, inside, last.
To start, multiply the first terms, 6 and 6. The answer is 36.
Next, multiply the outside terms, 6 and 5. The answer is 30.
Then, multiply the inside terms, h and 6. The answer is 6h.
Finally, multiply the last terms, h and 5. The answer is 5h.
Add all the products together.
36 + 30 + 6h + 5h = 11h + 66
The equation becomes 11h + 66 = 0.
Now, subtract 66 from both sides to isolate h.
11h = -66
Then, divide both sides by 11 to further isolate h.
h = -6
You have your final answer, h = -6.

What is geometric series?The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.
The given sequence is as follows:
10/3, 4, 24/5, 144/25, ...
The sequence is a geometric sequence with a common ratio of 6/5.
The first term is 10/3, so we can use the formula f(x + 1) = (6/5)(f(x)) to represent the sequence.
We have
f(x) = 10/3
Also, for f(x+1) we can have
x = 1,
f(1)= 10/3
f(2)= 4
So, f(x + 1) = 6/5(f(x))
Thus, the correct options are A and C.

if an arc of 60 degrees has an arc length of 50pi what is the circumference
Answer: 300[tex]\pi[/tex]
Step-by-step explanation:
Let's use the arc-length formula to solve this problem, and plug in the values that we have. Arc length is 50[tex]\pi[/tex] and the arc is 60°
Arc-length = [tex]2\pi r (\frac{x}{360})[/tex]
[tex]50\pi =2\pi r(\frac{60}{360})[/tex]
Cancel the [tex]\pi[/tex] and simplify the fraction.
[tex]50 = 2r(\frac{1}{6})[/tex]
Simplify further.
[tex]50 = r(\frac{1}{3} )[/tex]
Pass the 3 to the other side.
[tex]150=r[/tex]
So our radius is 150.
To find the circumference, we use the formula [tex]2\pi r[/tex]
Plug in r.
[tex]2\pi (150) = 300\pi[/tex]
To find the full circumference of a circle, multiply the given arc length for 60 degrees (50π) by 6, yielding a total circumference of 300π.
Explanation:To find the circumference of a circle when given the arc length of a particular section, we can use the relationship between the arc's degree measure and the circle's total circumference. Since the arc length of 60 degrees is 50π, we recognize that 60 degrees is one-sixth of a circle's full 360 degrees. Therefore, to find the full circumference of the circle, we multiply the arc length by 6 (because 360° / 60° = 6).
50π times 6 equals 300π, which is the circumference of the circle. This process uses the fact that the circumference of the circle is proportionate to the circle's rotation angle, which completes at 360°, corresponding to an angle of 2π radians.

How do the slopes of the lines created by each table compare?
Answer:
The Correct Answer is B
Step-by-step explanation:
Answer:
The correct answer is B. The slope of the Wholesale table is Three-fourths of the slope of the Public table.
Step-by-step explanation:
What is the equation, in point-slope form, of the line that is parallel to the given line and passes through the point (4, 1)?
y − 1 = −2(x − 4)
y – 1 = Negative one-half(x – 4)
y – 1 = One-half(x – 4)
y − 1 = 2(x − 4)
Given:
The line parallel to the given line containing the points (-3,3) and (-2,1).
Also, the parallel line passes through the point (4,1).
We need to determine the equation of the line in slope - intercept form.
Slope:
Since, the two lines are parallel, then their slopes are equal.
Thus, the slope of the parallel line can be determined using the formula,
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Substituting the points (-3,3) and (-2,1), we get;
[tex]m=\frac{1-3}{-2+3}[/tex]
[tex]m=\frac{-2}{1}[/tex]
[tex]m=-2[/tex]
Thus, the slope of the line is [tex]m=-2[/tex]
Equation of the line:
The equation of the line can be determined using the formula,
[tex]y-y_1=m(x-x_1)[/tex]
Since, the line passes through the point (4,1), let us substitute the point (4,1) in the above formula, we have;
[tex]y-1=-2(x-4)[/tex]
Thus, the equation of the line is [tex]y-1=-2(x-4)[/tex]
Hence, Option a is the correct answer.
To find the equation in point-slope form of a line parallel to the given line and passing through a point, we use the fact that parallel lines have the same slope.
Explanation:To find the equation in point-slope form of a line parallel to the given line and passing through the point (4, 1), we need to use the fact that parallel lines have the same slope.
The given line has an equation in point-slope form as y - 1 = -2(x - 4). The slope of this line, which is -2, will be the slope of the parallel line we are looking for.
Using the point-slope form equation y - y1 = m(x - x1), and substituting the values y1 = 1, x1 = 4, and m = -2, we can write the equation as y - 1 = -2(x - 4).
A restaurant needs four chairs for each table. Let c represent the number of chairs it needs if there are t tables. Which variable is dependent ? Which is independent? Write an equation to represent the relationship, (whoever is the first and has the correct answer gets 100 points and ill give you brainliest. PLEASE I NEED THIS TODAY)
Answer:
DV = numbers of chairs needed (c)
IV = number of tables (t)
IV × 4 = DV OR t × 4 = c
Step-by-step explanation:
DV dependent variable
IV independent variable
brainliest please?
The dependent variable means that it depends on how the independent variable is being manipulated. The independent variable is a variable that represents an amount that is being manipulated.
The dependent variable is "c" because it depends on the number of chairs it needs if there are t tables.
The independent variable is "t" because it manipulates the amount chair there are by the amount of tables there are.
Equation: 4t = c
4t represents the amount of chairs there are for the amount of tables there are. c represents the total amount of chairs.

bonnie runs 1 2/3 times as far as john each day if bonnie runs 5 miles on monday 3 1/2 miles on tuesday and 5 3/4 miles on wednesday how many miles did john run in all those three days
Answer:
3 miles on Monday
2¹/₁₀ miles on Tuesday
3⁹/₂₀ miles on Wednesday
Step-by-step explanation:
We are told that Bonnie runs 1⅔ (⁵/₃) times as far as John each day
This means that John runs ³/₅ times as far as Bonnie.
MONDAY:
Bonnie runs 5 miles on Monday, therefore, John runs:
³/₅ * 5 = 3 miles
TUESDAY:
Bonnie runs 3½ (⁷/₂) miles on Tuesday, therefore, John runs:
³/₅ * ⁷/₂ = ²¹/₁₀ = 2¹/₁₀ miles
WEDNESDAY:
Bonnie runs 5³/₄ (²³/₄) miles on Wednesday, therefore, John runs:
³/₅ * ²³/₄ = ⁶⁹/₂₀ = 3⁹/₂₀ miles
